Abstract (en)

[origin: US2019170714A1] Color changeable indicator particles having a meltable, particulate organic core, and at least one color changeable indicator coated on the particulate organic core. Color changeable indicator particles can be incorporated into composite polymer materials while maintaining the efficacy and stability of the indicator. The indicators provide simple, reliable, and cost effective detection means for detecting ammonia and carbon dioxide, and may find use in applications such as food packaging and medical applications.
